Fixing the filesystem freeze API - Fernando Luis Vazquez Cao, NTT Open Software Center

Sign up or log in to save this to your schedule and see who's attending!

There are several issues with the way filesystem freeze works in   Linux, among them: there is no check API, which means there is no easy way to know whether a filesystem is frozen or not; it is possible to umount a frozen filesystem despite the fact that there is no API to thaw an unmounted filesystem; it is not possible to freeze multi-device filesystems such as BTRFS; it does not play well with DM snapshot.

This presentation provides an overview of the current work to fix the filesystem freeze API, which should make an essential part of many backup and snapshot solutions much more robust.
